Human control bandwidth (2)
How much control is humanly possible? The limitations must be of
cognitive nature (Fitts 1954; Miller 1956; Fitts & Posner 1967;
Pressing 1988; Cook 2001), and they are hard to evaluate
Most of this research has been done in the field of music
instruments and performance, arguably the more
sophisticated/rich control devices invented
To bring into play the full bandwidth of communication there
seems to be no substitute, for mammals at least, than the
playing of music live (Bischoff et al. 1978)
First, although trad. music instruments are not digital, we have to
consider that each dimension has a resolution (in bits) e.g. MIDI
offers a 7-bit resolution/parameter, but 8, 12, 16 bits … are also
common
